(a) Contrast enhanced computed tomography revealed a huge aneurysm of the common hepatic artery. (b) Coeliac angiography demonstrated a saccular aneurysm 11 mm distal to the origin of the proper hepatic artery and 7 mm proximal to the junction of the left and right hepatic artery. Note. CA = coeliac artery; CHA = common hepatic artery; SA = splenic artery; GDA = gastroduodenal artery; LHA = left hepatic artery; RHA = right hepatic artery; HAA = hepatic artery aneurysm.

Coil embolisation using the distal balloon occlusion technique. (a) Angiography during catheterisation shows a microcatheter inserted into the right hepatic artery (RHA) under distal balloon occlusion (white arrow) in the RHA. (b) Angiography during coil embolisation shows a tight and compact coil. (c, d) Similar to the left hepatic artery (LHA). (e, f) Under proximal balloon occlusion in the proper hepatic artery.

(a) Abdominal enhanced computed tomography one year after treatment showing the hepatic artery aneurysm diameter reduced to 3 cm. (b) The white arrow shows the collateral artery from the superior mesenteric artery, and the white dotted arrow shows the collateral artery from the gastroduodenal artery to the right hepatic artery.
